Specification of Letters Patent.

Patented Feb. 2431914 Application filed August 16, 1913. Serial No. 785,067.

To all whom it may concern:

Be it known that I, CHRISTIAN SGHOEN, a citizen of the United States, residing at Nen'ark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Embroidery Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention has reference, generally, to improvements in embroidery frames, and, the invention relates, more particularly, to a novel work-holding frame for use with embroidery machines, with a view of providing an easily manipulated embroidery frame, in which several pieces of the work to be embroidered can be readily placed and secured in a perfectly stretched and taut relation, so that the parts of the several stretched pieces of work may be perfectly and simultaneously embroidered upon by the needles of the embroidery machine, when the frame, with the work in position therein, has been placed in the machine.

The invention has for its principal objects to provide a simply-constructed and easily manipulated embroidery frame in which articles of wear, such as handkerchiefs, and the like, can be readily secured with ease in perfectly stretched or tautrelation, and are positively clamped in their positions 'in the frame, so that the articles to be embroidered upon will not work loose or sag during the operation of embroidering when the frame is placed in the embroidery machine.

Other objects of this invention not at this time more particularly enumerated will be clearly understood from the following detailed description of the present invention.

VVith the various objects of the present invention in view, the invention consists, primarily, in the novel embroidery frame hereinafter set forth; and, the invention consists, furthermore, in the novel arrangements and combinations of the several devices and parts, as well as in the details of the construction of the same, all of which will be more fully described in detail in the following specification, and then finally embodied in the clauses of the claims which are appended to and which form an essential part of the said specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a plan viewof a fragmentary portion of an embroidery frame made according to and embodying the principles of this invention, showing in connection there with, a number of handkerchiefs properly arranged and clamped in position in the frame, ready to be placed in the embroidery machine. Fig. 2 is a detail plan view of a portion of the embroidery frame, said view being made on a larger scale, the handkerchief being omitted, so as to show more particularly the general construction of the work-clamping mechanism. Fig. 3 is a transverse vertical section, taken on line 3 3in said Fig. 2; Fig. 4c is a transverse vertical section, taken on line 4-4 in said Fig. 2, the spring-controlled latch-bolt, however,'being shown in side elevation; Fig. 5 is a transverse vertical section, taken on line 55 in said Fig. 2, with certain parts represented in side elevation; and Fig. 6 is a longitudinal vertical section, said section being taken on line 6-6 in said Fig. 2, with the work-clamping bar represented in side elevation.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

Referring now to the several figures of the drawings, the reference-characters l and 2 indicate a pair of barsof the embroidery frame, which may be made of wood, or any other suitable material. At suitable intervals, the bar is provided in its upper face with a plurality of transversely extending grooves or depressions, as 3, any number of such grooves or depressions being employed, according to the length of the embroidery frame. In a similar manner, and corre sponding in number to and in alinement with said grooves or depressions 3, the bar 2 is provided in its upper face with transversely extending grooves or depressions, as 4:. The reference-character 5 indicates a number of U-shaped or channel-bars, corre sponding in number to the number of grooves or depressions 3 and 4:, and said channel-bars having their respective endportions suitably arranged in the alined grooves or depressions 3 and 4 of the respective bars 1 and 2, and permanently secured therein by means of screws 6 and 7, as shown in Fig. 6 of the drawings. It will be understood, however, that any other suitable means may be employed for securing the end-portions of the channel bars 5 to the frame-bars l and 2. From an inspection of said Fig. 6 of the drawings, it will be seen, that each channel-bar, when Viewed from the top,,is made with the suitably wide end-portions 8 and 9, and the intermediate narrow clamping portion 10, formed by the side-walls of the respective portions 8 and 9, .and 10, and the side-walls of the said portion 10 being integrally united at their respective ends with the sidewalls of the parts 8 and 9. The end-portion 9 of each channelbar is also preferably made to taper toward a pair of perforated pintle or pivot-pin receiving end-members 11 in which are arranged the ends of a pintle or pivot-pin 12 which extends across the space between the said end-members 11. Pivot-ally mounted upon each pintle or pivot-pin 12 is a clamping-bar or member, as 13, each clamping bar or member being preferably made of suitable fiat metal, and each clamping bar or member being adapted to be lowered into the channel of its respective channel-bar 5, and being of such length, that the end-portion 14 of the bar or member 13 will project from the endportion 8 of the channel-bar, substantially as shown in Figs. 1, 2 and 6 of the drawings, and'the said end-portion 14 of the bar or member 13 being formed with a suitable fingerpiece, as 15. As will be noticed from an inspection of said Fig. 2 of the drawings, that portion between the walls of the clamping portion 10 of the channel-bar 5 is approximately equal to the width of the clamping bar or member 13, so as to produce at this point a perfect clamping effect, the'bar or rod 13' being furthermore provided at this'point and upon its lower surface with a supporting member or shoe, as 16, which serves also as a fulcrum for pressing the inserted material upon the inner surface ofthe channehbar 5, and permitting of a resilient action of the endportion 14 of the bar member 13, so, that when it is sprung under the or other suitable fastenin means 11 3011 the' upper face of the frame-bar 1, to one side i of the channel or groove 3 and the end-portion 14 of the bar or member 13, as shown in Figs. 1, 2 and 4, the said body-plate being provided with a pair of perforated ears or lugs, as 19 and 20, in which is slidably mounted a latch-bolt 21. Upon one end, this latchbolt is provided with a suitable finger-piece, as 22, and upon its other end it is chamfered or tapered off, as at 23, to provide a holding or locking nosing 24. A coiled spring 25 is mounted upon that portion of the bolt-body, located between a pin 26, which is connected with said bolt-body, and the perforated ing 19, the tendency of said spring normally being to move the latch-bolt in the direction of the arrow .00 in Fig. 4 of the drawings, so that thechamfered or tapered part 23 of the nosing 24 will project directly over the channeled end-portion 8 of the channel-bar 5, in the manner illustrated. It will be evident, that when a raised clamping bar 13 is lowered, the lower edge-portion 27 of the bar is brought down upon said chamfered or tapered part 23, and during its further downward movement, the latch-bolt is caused to slide in the opposite direction from that indicated by said arrow :19, until the said bar or member 13 has been moved past the nosing 24, when the action of the spring 25 once more returns the latch-bolt into its normal initial position,with the nosing 24 sprung over the upper edge of the clamping bar or member 13, so as to positively retain said bar or member 13, with its shoe 16 resting in its holding or clamping relation upon the material placed between the portion 10 of the channel-bar 5 and said shoe, as will be clearly understood.

To release the clamping bar or member 13 all that is necessary is to pull the latch-bolt 21 back, by means of its fingerpiece, so as to remove the nosing 24 from its holding engagement with the clamping bar or member 13, when the resilient action of said bar or member will spring the same slightly in an upward direction, and the bar or member 13 can then be raised by means of its fingerpiece 15, for the removal of the previously clamped piece of work.

In Fig. l of the drawings, I have shown one arrangement of a number of such work holding or clamping devices, and a'number of suitably folded handkerchiefs 28 in their clamped relation in. the embroidery frame, the cornereportion 29 of each handkerchief, the parts 30 of which are to be embroidered being clamped by means of suitable clamping devices which are suitably secured, in the desired positions, upon the upper surface of the frame-bar 2, in the positions indicated in Figs. 1 and 2 of the drawings. One form of such clamping devices is represented in Figs. 1, 2 and 5 of the drawings, and each clamping device consists, essentially, of a pair of members, as 31 and 32. arranged upon each other, as in Fig. 5, and having angular-1y bent and perforated parts,

metal, and is also formed with an opening 40 in which is rotatably disposed the hub 42 of a tightening lever 41, the latter being provided with a suitable fingerpiece, as 43, and a binding member, as'44, which is slidably disposed upon the upper surface of said member 31, to force the jaw 38 into its clamping relation with the jaw 39, when the lever 41 is in the position indicated in Figs;

2 and 5 of the drawings. That the clamping lever 41 may be suitably rotated, its perforated hub 42 is suitably disposed upon a screw-bolt 45 formed with a head 46, said bolt 43 extending through the frame-piece 2, and being secured in place by means of a nut 47 which is screwed upon the screwthreaded shank of said pin or bolt extending from the lower face of the said frame-bar 2, as shown. It will be understood, that any other suitable means for rotatably securing the tightening lever 41 in its operative position may be employed, and in lieu of the form of clamping device just described and illustrated in the accompanying drawings, any other suitably constructed clamping device may be employed.

The manipulation of the several devices and partsfor positively stretching and se curing the work, which is to be embroidered, in the embroidery frame will be clearly un derstood from the foregoing description and from an inspection of the several figures of the drawings, and any further detailed de scription of the same is, therefore, deemed unnecessary.

I am fully aware that changes may be made in the general arrangements and com binations of the various devices andtparts, as well as in the details of the construction of the same, without departing from the scope of the present invention as set forth in the foregoing specification and as defined in the clauses of the claims which are ap pended thereto. Hence, I do not limit my present invention to the exact arrangements and combinations of the several devices and parts, as described in the said specification, nor do I confine myself to the exact de tails of the construction of the said parts,
